Description
Technical Field
The invention belongs to the technical field of composite material preparation, and particularly relates to a preparation method of a high-temperature-resistant heat-insulating composite material.
Background
In recent years, China's aerospace industry has been developed at a high speed, and the friction between an aerospace plane and air can generate a phenomenon of pneumatic heating, so that the surface of the aerospace plane can be rapidly raised to a very high temperature, and taking the aerospace plane as an example, peak temperatures of a nose cone cap, a wing front edge part, a leeward side measuring region and a windward side part of the aerospace plane can reach 1600 ℃, 1260 ℃, 500 ℃ and 500-plus-1200 ℃ respectively at the highest. Due to the temperature increase, the materials selected for the spacecraft place higher demands on high temperature resistance and thermal insulation. And certain requirements are also required on the mechanical property and the pressure resistance of the material along with the increase of the flying height. The heat-insulating material can be divided into organic materials and inorganic materials which have respective advantages and disadvantages, the inorganic heat-insulating material has the advantages of good fireproof and flame-retardant performance, but has the disadvantages of large heat conductivity coefficient and poor heat-insulating effect, and the most applications in the market at present mainly comprise: clay, mineral wool, calcium silicate, and the like; the organic heat-insulating material has small heat conductivity coefficient and good heat-insulating effect, and comprises polyurethane, organic silicon resin and the like, but the organic material is limited to be used alone due to the defect that the organic material is easy to burn, so in order to enable the material to have more excellent performance, researchers research the composite material prepared from the organic polymer and the inorganic material.
Montmorillonite (Al, Mg)2(SiO10)(OH)2·n H2O is a layered aluminosilicate mineral existing in nature, and the layered structure is mainly composed of a three-layer structure of tetrahedron (Si-O) -octahedron (Mg-O, Al-O) -tetrahedron (Si-O). Montmorillonite has high water absorption capacity because the montmorillonite has a large amount of metal cations in the montmorillonite layer for playing a comprehensive role in negative charge due to the negative charge on the montmorillonite layer, and the montmorillonite has strong cation exchange capacity due to the existence of the metal cations. Montmorillonite has low density, low thermal conductivity, relatively high melting point, certain toughness, chemical inertness, durability and environmental safety. Montmorillonite as a light porous material has excellent heat insulation performance and high-temperature stability, so that the montmorillonite has the capability of resisting high temperature difference, and becomes a heat insulation layer material in a high-temperature environment.
The phosphate resin is an inorganic salt resin with large molecular weight prepared from phosphoric acid or concentrated phosphoric acid, and the phosphate resin and a curing agent (commonly used metal oxides, hydroxides and metal salts) can generate a cross-linking reaction at normal temperature to form the phosphate adhesive with a network structure. The phosphate adhesive has the advantages of high bonding strength, high temperature resistance, stable chemical property and no toxicity, and is widely applied in many aspects. At present, organic polymer materials are more and more widely applied, and most polymers are known to have the defects of flammability and thermolabile performance at high temperature, so modification research is carried out on the polymer materials to realize the high temperature resistance of the polymer materials, and most of the high temperature resistant polymer materials in the market are organic silicon materials and phenolic resin materials which have good high temperature resistance and are widely applied.
At present, the application research of montmorillonite in the field of heat-insulating composite materials is divided into two aspects: firstly, the treated montmorillonite powder or particles are directly added into the polymer as filler to improve the mechanical property, thermal property and gas-barrier capability of the polymer, and because the montmorillonite is not fully peeled and arranged in the organic polymer matrix, the montmorillonite concentration in the composite material is usually very low and generally does not exceed 10 wt% in order to prevent aggregation. Researchers prepared PA-6/MMT nano composite materials by a direct melt blending method, and through melt mixing and molding of MMT treated by maleic anhydride and PA-6 at the same time, the results show that in a tensile test, the tensile modulus and strength of the nano composite materials tend to increase along with the increase of the content of MMT, the tensile strength is respectively 27.9MPa, 34.08MPa and 35.28MPa when the content of the treated montmorillonite is 0%, 2% and 5%, but the elongation at break of the materials decreases along with the increase of the tensile strength, and the addition of the montmorillonite slightly increases the glass transition temperature of the materials but the maximum decomposition temperature is almost unchanged. And secondly, the montmorillonite is used as a main material, and because the montmorillonite material has low mechanical strength, the polymer is used as an adhesive and a reinforcing material to simultaneously exert the excellent performance of the polymer. Researchers prepare a flexible montmorillonite-polyethylene glycol nano composite film by means of ultraviolet crosslinking, specifically, nano particles, polyethylene glycol n-butyl dimethacrylate and a photoinitiator 2-hydroxy-2-methylacetophenone are mixed and placed in a treated glass plate interlayer to be crosslinked and cured under the condition of ultraviolet light to generate a flexible hybrid film, the result shows that the film (1cm multiplied by 60 mu m) keeps the original shape under the flame of 120s under the condition that the filling amount of the montmorillonite is 70%, and the tensile strength of the composite material is respectively 0.74MPa, 3.64MPa and 4.58MPa under the contents of 0%, 69% and 74.3% because the mechanical property of the composite material added with the montmorillonite is improved, the content of the montmorillonite plays a critical role in the performance of the composite material, and the improvement of the content of the montmorillonite is very good for improving the thermal performance of the composite material, however, the tensile strength of the material is not high and the ability to withstand heat is limited, so that it is important to achieve high mechanical and thermal properties under the condition of high montmorillonite filling.
Disclosure of Invention
The invention aims to provide a preparation method of a high-temperature-resistant heat-insulating composite material in order to realize high montmorillonite filling and improve the mechanical property of the material.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a preparation method of a high-temperature-resistant heat-insulation composite material comprises the following steps:
the method comprises the following steps: placing montmorillonite in 1mol/L NaCl solution, treating at 80 deg.C in oil bath at stirring speed of 2000rpm for 4 hr, repeatedly washing the montmorillonite with distilled water for several times to remove Cl-Drying in a 40 ℃ oven for 12 h;
step two: adding an organic polymer into the treated montmorillonite material, uniformly mixing, adding ethyl acetate to ensure that the organic polymer and the montmorillonite are more fully mixed, stirring for 30min at normal temperature, and putting the mixture in a drying oven at 40 ℃ for 12h to volatilize the ethyl acetate to obtain organic hybrid montmorillonite;
step three: mixing a phosphate resin and a metal oxide according to a ratio of 1: 1, and developing in a mortar to enable the components to be in full contact with each other to prepare the phosphate adhesive;
step four: adding a phosphate adhesive into the prepared organic hybrid montmorillonite, fully stirring and uniformly mixing, putting the uniformly mixed material into a mold, and pressing the material into a cylindrical sample on a pneumatic press at the pressure of 2 MPa;
step five: curing the formed material at a step-shaped temperature for 30min in an oven at 80 ℃, 120 ℃ and 150 ℃ respectively, and then curing for 2h at 180 ℃.
Compared with the prior art, the invention has the beneficial effects that: the method is used for preparing the organic-inorganic hybrid montmorillonite composite material which is hybridized by phosphate and high-temperature resistant polymer together, so that the montmorillonite composite material has certain strength and deformation capability. The existing research mostly adds a small amount of inorganic rigid particle filler into a polymer to improve the mechanical property and the thermal property of a polymer material, but because the rigid particles are difficult to be uniformly dispersed in the polymer, the adding amount of the rigid particles is relatively small, mostly below 10 percent, so that the self-excellent performance of the inorganic filler cannot be fully exerted, and the toughening effect of the rigid particles is rarely researched. The inorganic filler with high filling amount in the experiment can still maintain a good morphological structure at a high temperature of 1000 ℃ because the inorganic filler has good fire resistance, and has good toughness to generate certain deformation, so that the impact resistance and the mechanical strength of the material are improved.

Detailed Description
The technical solutions of the present invention are further described below with reference to the drawings and the embodiments, but the present invention is not limited thereto, and modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
The first embodiment is as follows: the embodiment describes a preparation method of a high-temperature-resistant heat-insulating composite material, which comprises the following steps:
the method comprises the following steps: chemically treating montmorillonite, placing montmorillonite in 1mol/L NaCl solution, treating at 80 deg.C in oil bath at stirring speed of 2000rpm for 4 hr, repeatedly washing the treated montmorillonite with distilled water for several times to remove Cl-And using AgNO in combination3Detecting in solution when Cl is present-After the materials disappear, the treated materials are put into an oven with the temperature of 40 ℃ for drying for 12 hours; the sodium chloride is used for treating the montmorillonite mainly because the montmorillonite has higher cation exchange capacity, and the interlayer spacing of the montmorillonite can be enlarged and even partial montmorillonite can be stripped due to the entering of sodium ions. The small particle size of the montmorillonite can ensure that the mixing uniformity of the composite material is higher and the performance index of the material is improved.
Step two: adding an organic polymer with good heat resistance into the treated montmorillonite material, uniformly mixing, adding a certain amount of volatile ethyl acetate which does not react with the material to enable the organic polymer and the montmorillonite to be more fully mixed, stirring for 30min at normal temperature, and putting the mixture in a drying oven at 40 ℃ for 12h to enable the ethyl acetate to be volatilized to obtain organic hybrid montmorillonite; the ethyl acetate is equivalent to a solvent or a diluent of the used high-temperature resistant polymer, and the high-temperature resistant polymer material is diluted to ensure that the high-temperature resistant polymer material is more uniformly mixed in order to ensure that the high-temperature resistant polymer material is fully contacted and mixed with the treated montmorillonite due to the poor flowability of the high-solid content polymer. The function of adding the high-temperature resistant polymer is firstly to have certain adhesive property, and the layered montmorillonite material can be further peeled off in the mixing process with the montmorillonite due to larger viscosity, and secondly, the selected high-temperature resistant polymer material has lower heat conductivity coefficient and has higher carbon residue to play a better role in the heat insulation property of the material.
Step three: mixing a phosphate resin and a metal oxide according to a ratio of 1: 1, grinding in a mortar to enable the mixture of the phosphate resin and the metal oxide to be fully contacted and mixed to prepare the phosphate adhesive;
step four: adding a phosphate adhesive into the prepared organic hybrid montmorillonite, fully stirring and uniformly mixing, putting the uniformly mixed material into a mold, and pressing the material into a cylindrical sample with the diameter d being 1.3cm and the height being 1.0cm on a pneumatic press under the pressure of 2 MPa;
step five: curing the formed material at a step-shaped temperature for 30min in an oven at 80 ℃, 120 ℃ and 150 ℃ respectively, and then curing for 2h at 180 ℃. Since the high temperature resistant organic polymer forms a porous structure of bubbles during heating, in order to reduce the amount and number of bubbles and the size of pores and bubbles, a curing reaction is required and a slow temperature rise operation is employed.
The second embodiment is as follows: in a preparation method of a high-temperature-resistant heat-insulating composite material according to a first specific embodiment, in the first step, the ratio of montmorillonite to NaCl solution is 10 g: 100 mL.
The third concrete implementation mode: in the second step of the preparation method of the high temperature resistant and heat insulating composite material, the organic polymer is cured at a temperature of 80 ℃ or higher, and after curing, the organic polymer presents a cross-linked network structure, and the polymer after ablation generates carbon. The crosslinked net structure can enable the polymer to have excellent bonding performance and high bonding strength which can reach 10-20MPa, and the ablated organic polymer can generate a large amount of carbon which has good heat insulation and flame retardant effects, so that the high-temperature resistant polymer material has high application value in the fields of high-temperature resistance, heat insulation and flame retardant.
The fourth concrete implementation mode: in the third step, the metal oxide is Al2O3ZnO and MgO. The mixture of metal oxides is mixed in a certain proportionA reagent product.
The fifth concrete implementation mode: in a specific embodiment, a method for preparing a high temperature resistant heat insulation composite material comprises the following steps: phosphate adhesive: 100-450% of an organic polymer: 100: 50 or montmorillonite: phosphate adhesive: 100-450% of an organic polymer: 100: 100.

The content of the high-temperature resistant organic polymer is further increased according to the weight ratio of phosphate: montmorillonite: organic polymer 100: (100-450): 100, compressive strength of 7.22MPa, 14.515MPa, 14.813MPa, 17.49MPa, 20.43MPa, 24.95MPa, 27.84MPa and 28.65MPa, and deformation of 5.33%, 9%, 11%, 10.67%, 11.67%, 13.67%, 15.67% and 17%. According to the data, the compressive strength shows the trend of increasing firstly and then decreasing with the increase of the content of the montmorillonite according to any proportion, and the compressive strength is slightly reduced with the increase of the content of the high-temperature-resistant organic polymer, however, the strain in the sample is greatly improved by adding 100 parts of the organic polymer.
The cured sample is heated to 1000 ℃ in a muffle furnace at a temperature of 10 ℃/min and is kept for 10min, the appearance of the sample is complete and is not changed, and as shown in figures 3 and 4, the sample has excellent high-temperature resistance.
